Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of assembly of heat sink production, in particular to an online assembly production line of electroplated products and carriers. BACKGROUND

[0002] With the progress of science and technology and the development of economy and society, various electronic products have emerged, and electronic products with faster processing speed are more favored by consumers. Fast processing speed also requires the use of high-power electronic components in electronic products. High-power electronic components will generate more heat during operation. If the heat generated by the electronic components cannot be dissipated in time, the electronic components will be damaged due to high temperature, and the electronic products will be damaged.

[0003] At present, heat sinks are mostly assembled on electronic components. In the production and manufacturing process of heat sinks, a material belt is used to support a plurality of heat sinks to facilitate the transfer of the heat sinks. In the process of assembling the heat sinks and the material belt, a driving structure is used to intermittently feed the material belt to install the heat sinks.

[0004] A patent with publication number CN209658137U is disclosed in the prior art, which includes a workbench, a transmission mechanism, a feeding mechanism, a grabbing mechanism, and a pressing mechanism installed on the workbench. The transmission mechanism includes an input end and an output end, and a heat sink crystal is arranged on the transmission mechanism. The feeding mechanism is provided with magnetic beads. The feeding mechanism, the grabbing mechanism, and the pressing mechanism are arranged along the transmission mechanism. The feeding mechanism and the grabbing mechanism are oppositely arranged and close to the input end of the transmission mechanism, and the pressing mechanism is close to the output end of the transmission mechanism. The present application provides a heat sink assembly machine that solves the technical problem of low efficiency of manual magnetic bead sleeving in the prior art.

[0005] The existing device gradually exposes the shortcomings of the technology with use, mainly in the following aspects:

[0006] First, when the products on the existing material belt are assembled, different processing procedures are required, so that the devices are not arranged in the same longitudinal direction, which makes it difficult to support the material belt at the corner position, affecting the stability of the material belt during feeding.

[0007] Second, when the material belt is fed to the assembly machine, the assembly machine feeds the material belt in an interval to assemble the product. Since the unwinding process of the material belt is continuous, the material belt is prone to overwinding, which affects the stability of the material belt feeding.

[0008] Third, the existing gripping fixture picks up the heat spreader from the tray and installs it directly into the conveyor belt. Due to the low positioning accuracy of the product in the tray, interference often occurs between the product and the conveyor belt when products in different positions are assembled with the conveyor belt, making it impossible to quickly assemble the product onto the conveyor belt and affecting assembly efficiency.

[0009] Fourth, existing conveyor belts cannot accurately position the movement and location of the conveyor belt during product assembly, resulting in the conveyor belt and product not being able to fit together precisely during assembly, thus reducing the product assembly efficiency.

[0010] Fifth, the existing equipment cannot be adjusted according to the width of different material strips, which requires customization based on different material strips and reduces the scope of application.

[0011] Sixth, the existing material strip is prone to displacement during the opening process, which in turn affects the stability of the heat spreader assembly process.

[0012] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0057] Compared with the prior art, the beneficial effects of the present invention are:

[0058] The material belt is fed through the material belt feeding area of ​​the first-end power material pulling device and the last-end power material pulling module. The material belt passes through the material belt support plate or material belt roller on several guide frames after passing the corner. When the subsequent assembly machine feeds the material belt intermittently, the material belt will deviate at the corner position. The guide frame slides on the slide rail to assist the material belt deviate and ensure that the material belt can still be supported during the deviation process.

[0059] The guide slides on the slide rail to change the relative position of the material belt and the buffer frame to achieve the buffer function. Two position sensors detect the front and rear positions of the material belt, and the PLC signal monitors the position of the material belt to control the movement of the front and rear machines.

[0060] By adjusting the rotation of the bearing, the offset angle between the material belt support plate and the material belt is made consistent, thus preventing the material belt from jamming.

[0061] The buffer margin is adjusted by adjusting the forward and backward movement of the slide rail, and the difference between inching and continuous motion is achieved through margin control.

[0062] By resolving the difference between inching and continuous motion, our organization has demonstrated the feasibility of online assembly of products using a motion method.

[0063] The feasibility of achieving uninterrupted electroplating by monitoring the position of the material strip with position sensors and synchronously coordinating the actions of the front and rear machines;

[0064] By placing a tray on a linear guide rail, products are supplied. Through intermediate precision positioning, the feeding action is broken down into two steps, overcoming the impact of low product precision in the tray. Regardless of the product's positioning precision in the tray, a secondary precision positioning is achieved through the intermediate positioning module. Then, the feeding module grabs the precisely positioned product into the conveyor belt, improving work efficiency.

[0065] The product can be flipped to a suitable angle that matches the material strip by a flipping cylinder, thus completing the assembly of materials coming in from different angles;

[0066] The grippers use nitrile rubber protective sleeves to effectively protect the product and overcome the problem of silicone oil seeping out of the product surface after being gripped by silicone protective sleeves, which can lead to product contamination.

[0067] The opening mechanism is designed as a left-right split mode and installed on the spacing adjustment guide rail. The spacing is adjusted by the spacing adjustment screw to achieve versatility for material strips of different widths.

[0068] Before opening the spring clip of the conveyor belt, first press the conveyor belt clamp to tighten and fix the conveyor belt to prevent the conveyor belt from deforming and scratching the product during the process of lifting the conveyor belt;

[0069] Before placing the product, lift the material pallet to limit the bottom of the product and prevent the product from moving too far downwards during placement, which could cause scratches.

[0070] The top cylinder lifts the top head, which lifts the spring pieces on the material strip. After the material strip is lifted, the spring pieces open, allowing the product to be avoided in the vertical direction, thus meeting the material placement requirements.

[0071] The strip moves towards the pressure roller along the space between the positioning plate and the pulling frame. When pulling is required, the pulling guide moves the pulling plate along the pulling guide rail to a position close to the pressure plate. Then, the pulling cylinder extends, pulling the pulling needle out and inserting it into the pulling hole of the strip. The pulling guide then moves the pulling plate and the strip towards the pressure roller to achieve the pulling operation. When it reaches the correct position, the positioning cylinder moves the positioning pin, inserting it into the positioning hole of the strip to position it. After positioning the strip, the pulling needle retracts from the strip under the action of the pulling cylinder and returns to the starting position. The above steps are repeated for the next pulling action. The positioning pin does not contact the strip during the movement of the strip by the pulling needle; otherwise, it is inserted into the positioning hole of the strip for positioning. This achieves precise pulling and positioning, improving the stability of the strip and product assembly process. Attached Figure Description

[0124] The material belt 37 feed area is formed through the area between the positioning plate 59 and the material puller 56.

[0125] A positioning cylinder 48 is fixedly connected to each positioning plate 59 on the material pulling frame 56, and the telescopic end of the positioning cylinder 48 is fixedly connected to the inner wall of the positioning plate 59.

[0126] A mounting plate 47 is fixedly connected to the material pulling frame 56, a material pulling guide rail 50 is fixedly connected to the mounting plate 47, a material pulling guide seat 51 is connected to the material pulling guide rail 50, and a material pulling plate 57 is installed on the material pulling guide seat 51.

[0127] A material pulling cylinder 49 is fixed on the material pulling guide seat 51, and the telescopic end of the material pulling cylinder 49 is fixedly connected to the back of the material pulling plate 57.

[0128] The material pulling guide seat 51 is fixedly connected to a guide plate 52. Two guide rails 53 are fixedly connected in parallel to the material pulling needle 58 on the guide plate 52. The material pulling plate 57 is fixedly connected in parallel to a guide seat 54 that is slidably installed on the guide rails 53.

[0129] The feeding frame 56 is equipped with a pressure roller 46 near the discharge end. The two ends of the pressure roller 46 are equipped with limit plates, and the material belt 37 is constrained in the area between the two limit plates.

[0130] The two ends of the material pulling frame 56 corresponding to the pressure roller 46 are respectively fixed to the frame body, and the two ends of the pressure roller 46 are rotatably installed in the frame body by means of a rotating shaft.

[0131] A guide rod is fixed to the inner wall of the positioning plate 59, and a guide hole matching the guide rod is opened on the material pulling frame 56.

[0132] The working principle of this device is as follows:

[0133] The material belt is fed through the material belt feeding area of ​​the first-end power material pulling device 78 and the last-end power material pulling module 82. The material belt passes through the material belt support plate 74 or material belt roller 72 on several guide frames 77 in turn. When the subsequent assembly machine feeds the material belt intermittently, the material belt will deviate at the corner position. The guide frame 77 slides on the slide rail 75 to assist the material belt deviate and ensure that the material belt can still be supported during the deviation process.

[0134] The guide rail 77 slides on the slide rail 75 to change the relative position of the material belt and the buffer frame 76 to achieve the buffer function. Two position sensors 73 detect the front and rear positions of the material belt, and the PLC signal monitors the position of the material belt to control the movement of the front and rear machines.

[0135] By adjusting the rotation of bearing 69, the offset angle between the material belt support plate 74 and the material belt is made consistent, thus preventing the material belt from jamming.

[0136] The buffer margin is adjusted by adjusting the forward and backward movement of the slide rail 75, and the difference between inching and continuous motion is achieved through margin control.

[0137] By resolving the difference between inching and continuous motion, our organization has demonstrated the feasibility of online assembly of products using a motion method.

[0138] The position sensor 73 monitors the position of the material belt, and the actions of the front and rear machines are coordinated synchronously to realize the feasibility of electroplating without stopping the machine. By placing a material tray on the linear slide rail, the product 16 is supplied. Through intermediate precision positioning, the feeding action is split into two steps, which overcomes the influence of the low precision of the product 16 in the material tray. Regardless of the positioning accuracy of the product 16 in the material tray, a secondary precision positioning is achieved through the intermediate positioning module 62. Then, the feeding module 63 grabs the precision-positioned product 16 into the material belt 37, thereby improving the work efficiency.

[0139] The product 16 can be flipped to a suitable angle that matches the material strip 37 by the flipping cylinder 13, thus completing the assembly of materials coming in from different angles;

[0140] The gripper 15 uses a nitrile rubber protective sleeve 14 to effectively protect the product 16 and overcome the problem of silicone oil seeping out from the surface of the product 16 after being gripped by a silicone protective sleeve, which would cause contamination of the product 16.

[0141] The opening mechanism is designed as a left-right split mode and installed on the spacing adjustment guide rail 30. The spacing is adjusted by the spacing adjustment screw to achieve the versatility of material strips 37 with different widths.

[0142] Before opening the spring clip 39 of the material strip 37, first press the material strip 37 with the material strip clamping block 26 to fix the material strip 37, so as to prevent the material strip 37 from deforming and scratching the product 16 during the process of lifting the material strip 37.

[0143] Before placing product 16, lift up material pallet 29 to limit the bottom of product 16 and prevent product 16 from moving downwards excessively during placement, which could cause product 16 to be scratched.

[0144] The top cylinder 35 lifts the top head 38, thereby lifting the spring piece 39 on the material belt 37. After the material belt 37 is lifted, the spring piece 39 opens, allowing the product 16 to be avoided in the vertical direction, thus meeting the material placement conditions.

[0145] The material strip 37 moves towards the pressure roller 46 along the space between the positioning plate 59 and the pulling frame 56. When pulling is required, the pulling guide 51 drives the pulling plate 57 to move along the pulling guide rail 50 to a position close to the pressure plate. Then, the pulling cylinder 49 extends, driving the pulling needle 58 to extend and insert it into the pulling hole of the material strip 37. The pulling guide 51 then drives the pulling plate 57 and the material strip 37 to move towards the pressure roller 46 to realize the pulling operation. After moving into position, the positioning cylinder 48 drives the positioning needle 5 to slide. After the positioning pin 5 is inserted into the positioning hole of the material strip 37 and the material strip 37 is positioned, the pulling pin 58 is withdrawn from the material strip 37 under the action of the pulling cylinder 49 and returns to the starting position. The above steps are repeated for the next pulling action. The positioning pin 5 does not contact the material strip 37 only when the pulling pin 58 moves the material strip 37. At other times, it is inserted into the positioning hole of the material strip 37 for positioning. This achieves precise pulling and positioning, and improves the stability of the material strip 37 and product 16 during the assembly process.
